Patented sea buckthorn fraction use
Context: Utilisation d’une fraction hydrophile du fruit de Hippophae rhamnoides pour la fabrication d’une composition cosmétique, dermatologique ou pharmaceutique. Hippophae rhamnoides is 'sea buckthorn' or 'argousier'.
Pour réaliser les expérimentations décrites dans cet exemple, on utilise *un pressurat* de fruit de Hippophae rhamnoides dépulpé par décantation, qui contient encore quelques résidus solides qui ont tendance à décanter dans le temps."
This most likely translation I can find so far is 'press cake'. Can anyone confirm or suggest an alternative? Thank you.

Oil Extraction
Sea buckthorn offers two possibilities for oil extraction. Pulp oil exists in the juice pulp and is isolated as a cream layer by centrifugal technology. The usual methods for manufacturing oil commercially require countercurrent (usually) extraction of the oil bearing material, seed or pulp, with an organic solvent, commonly hexane (Weiss 1963, 1970).
Increasingly, consumers are demanding fewer residues in their foods. Newer extraction techniques such as supercritical fluid extraction (SCE) especially carbon dioxide under high pressure can be used to reduce oil residues. Sea buckthorn oil may be a secondary product since it is a specialty oil used in medicine, as a nutraceutical supplement, and in cosmetics (Beveridge et al. 1999).
Pigment
A pigment termed “sea buckthorn yellow” can be extracted from sea buckthorn waste material. The waste material could be the press cake remaining after juice extraction or the sediments remaining after centrifugation. In one process the pigment is extracted with low concentrations of alcohol (Chen et al. 1995; Liu et al. 1989) after concentrating the suspension to 11°–13° Brix. The waste material is spray dried to yield a yellow powder. It contains flavones but also, carotene and vitamin E. Supercritical CO2 has also been used to extract a yellow coloring material from sea buckthorn waste. Pressure had the greatest influence on extraction with yields increasing with extraction pressure. A yield of 64% total carotenoids was achieved under processing conditions of 60 MPA, 85°C (Messerschmidt et al. 1993).

NO! That is incorrect, it looks like the press cake is the actual residue....I'll keep looking...I think it would be good to know more about the supercritical fluid extraction technique and what instruments it requires...

OK, I am now coming back to my original answer, which is that your text is INDEED speaking about a sea buckthorn press cake. Sorry for the brain lapse!

Extraction
Oil can be extracted mechanically with an oil press, an expeller, or even with a wooden mortar and pestle—a traditional method that originated in India. Presses range from small, hand-driven models that an individual can build to power-driven commercial presses. Expellers have a rotating screw inside a horizontal cylinder that is capped at one end. The screw forces the seeds or nuts through the cylinder, gradually increasing the pressure. The material is heated by friction and/or electric heaters. The oil escapes from the cylinder through small holes or slots, and the PRESS CAKE emerges from the end of the cylinder, once the cap is removed. Both the pressure and temperature can be adjusted for different kinds of feedstock. The ram press uses a piston inside a cage to crush the seed and force out the oil.

OK! Finally! The term should be "press juice".
Sue is right: the solid part is the press cake and the liquid part (containing residue) is the press juice.

GREEN BIOREFINERIES process and convert the raw material “green biomass” (e.g. grass, clover, lucern) into a range of individual marketable products (multi-product–system) based on deployment of sustainable zero-waste technologies. An essential process unit in a GREEN BIOREFINERY installation is the mechanical fractionation of the primary raw material “green biomass” into a liquid phase (press juice) and a solid phase (press cake). The press juice contains water soluble compounds like lactic acid and amino acids, the press cake contains fibres of different length and diameter.
Residue sugar in press cake and press juice is quite high. Methods should be investigated by means of which these residue sugars could be converted into additional lactic acid.

juice
Sounds like juice to me (C.f. oranges) - pressed, pulp removed...
http://www.hort.purdue.edu/newcrop/ncnu02/v5-393.html
Juice
The fruit of the sea buckthorn plant weighs between 270 and 480 mg and averages 350 mg depending upon cultivar and maturity (Li 1999). Pressing these berries yields 60% to 85% juice. Juice yield of 67% has been reported derived from centrifugal methods (Heilscher and Lorber 1996). The juice is very high in organic acids as reflected in the high levels of titratable acidity, and has a low pH (near 2.7). Quantitatively the most important organic acid is malic acid, but there several other minor acids have been reported (Beveridge et al. 1999). Protein levels are fairly high for a fruit juice and this probably explains the fact that sea buckthorn juice is a cloudy or opalescent product.

"pressurat... dépulpé" - this is what you get when you press the fruit and remove the pulp from the resulting liquid.
Press cake is the solid part that has been removed.

: Indeed. In fact, I believe the correct term is "press juice" (See references at the end of my long list of notes)!
